Definitions

  • the invention relates to a stacked plate heat exchanger, in particular intercooler, with a plurality of stacked stacked disks, wherein in each case a first stacking disk and a second stacking disk are alternately stacked in a stacking direction, wherein the stacking disks each have a set up in a stacking direction and peripheral edge, two adjacent stack disks each abut each other at least with its edge, wherein each two adjacent stack disks define a first cavity for passing a first fluid or a second cavity for passing a second fluid, with first cavities and second cavities alternating in the stacking direction.
  • Such stacked plate heat exchangers are used for example in intercoolers. It is passed through the first cavity to be cooled charge air and through the second cavity a coolant. Thus lie on the inner stacking disks on each side of the charge air and on the other side to the cooling medium. As a result, the charge air flowing through the stacked plate heat exchanger can be cooled very effectively by the coolant.
  • a stacked plate heat exchanger having a plurality of stacked and interconnected, in particular soldered, elongated discs known that limit a cavity for performing a medium to be cooled in the longitudinal direction of the discs and another cavity for carrying a coolant.
  • a stacked plate heat exchanger in which in the cavities a turbulence insert is inserted, which may be formed for example by a corrugated sheet, and which improve the heat transfer from the coolant or the medium to be cooled to the respective stacking disks.
  • the present invention has for its object an improved or at least other embodiment of a stacked plate heat exchanger, or a charge air cooler or an internal combustion engine with such a stacked plate heat exchanger to provide, which is characterized in particular by a stabilization of the cavities between the stacking disks.
  • the invention is based on the general idea of providing a support device which stabilizes the distance of the individual stacking disks measured in the stacking direction relative to one another. It is expedient for the stacked-plate heat exchanger to have a support device which holds the stacking disks in an edge region of the stack disks is supported against each other in the stacking direction to stabilize the second cavity between the stack disks.
  • the support means so the slump of the stacking disks in the stacking direction is additionally limited. Deviations, in particular in the disc length and / or width and / or the angle of the erected edges, thereby have only a very small influence on the self-adjusting distance between the stacking discs. Thereby, the tightness and the stability of the stacked plate heat exchanger can be improved.
  • a favorable possibility provides that the support device does not seal the cavity. Because the support device does not have to seal the respective cavity, there are freedoms in the design of the support device that can be used to form a cost-effective and effective support device.
  • the support device is different from the edges of the stacking disks. Due to the steep angle of the edges to the stacking disks, small deviations in the angle or in the length or width of the stacking disks lead to a strong displacement of the support point. Consequently, a supporting device based solely on the formation of the edges would not be sufficient to allow a satisfactory support of the spacing of the stacking disks with each other.
  • the stacking disks each have, at longitudinal end regions, a first opening for the first fluid and at least two second openings for the second fluid arranged around the first openings.
  • the openings formed in the stacking disks thus penetrate in the stacking direction the entire stacking plate heat exchanger. Consequently, through the openings, the respective fluid can flow into the respectively associated cavities.
  • fluid flowing through the first openings into the stacked disk heat exchanger may flow only into the first cavities, and fluid flowing through the second openings in the stacked plate heat exchanger may only flow into the second cavities.
  • the first cavities formed between the stacking disks and the second cavities are fluidly arranged in each case parallel to one another, that is, through which the respective fluid flows in parallel.
  • two fluid passages are formed in the stacked plate heat exchanger, which are separate from each other, so that the coolant and the medium to be cooled do not mix.
  • At least a part of the second cavity is formed in a region of the at least one second opening between the stacking disks, and the support device is arranged in the region of the at least one second opening.
  • the second openings are located in the edge region of the stacking disks. In this edge region between each two stacking disks alternately a large distance, which forms the second cavity, and no distance, so stacked stacking discs, given. Due to the large distance between the stacking disks in the edge region, the stabilizing effect due to the raised edges is very low. Therefore, the effect of a support device arranged in the region of the at least one second opening is particularly high.
  • the stacking disks are shaped in such a way that a stacking disk, in a region of the at least one second opening, has a spacing from a first adjacent stacking disk and rests against another, second adjacent stacking disk lying on the opposite side , In this way, between the two stacking disks in the region of the second openings, either the second cavity is at least partially formed or an effective support of the stacked disks resting on one another is given to one another.
  • the supporting device is arranged only in the second cavity between the stacking disks in order to stabilize it.
  • a favorable variant provides that the distance of the adjacent stacking disks is defined by the support means.
  • the support device can be designed such that a desired defined distance between the stacking disks is set, so that the required height of the respective cavities can be maintained.
  • the stacking disks each have at least two second openings for the second fluid arranged around the first openings, webs are formed between the second openings, and at least some of the webs are embossed to form the support means.
  • a particularly favorable variant provides that every second web is embossed between the second openings.
  • the non-embossed webs can be supported against the lying on the opposite side stacking disks.
  • the stacking disks are sufficiently supported in both directions against the adjacent stacking disk.
  • the support means is formed by at least one insert part, which is inserted into the second cavity in a region of the at least one second opening.
  • the insert part can bridge the distance between the respective stacking disks in the region of the at least one second opening, so that the at least one insert part bears against the two respective stacking disks.
  • the respective stacking discs do not approach each other closer, so that is given by the insert sufficient support between the stacking discs.
  • the insert is formed substantially semi-annular, wherein on an inner side a plurality of inwardly projecting fingers for segmenting the at least one second opening are arranged.
  • a semi-annular insert has the advantage that the position of the insert is stabilized within the second cavity and thus the supporting action of the insert is secured. It is understood that in each end region of the stacking disks at least one insert is inserted in each case. Thus, both end portions of the stacking disks can be stabilized by the support means.
  • the support means is formed by a plurality, for example eight, inserts which are inserted into the second cavity in a region of the at least one second openings, and that the inserts are cylindrical.
  • Such shaped inserts are extremely cheap to manufacture, so that the support device can be produced inexpensively.
  • the support means is formed by at least one cam, which is formed in a variety of stacking disks in the peripheral edge.
  • the supporting action of the erected edges is improved, since the stacking disc arranged above the respective stacking disc can not slip over the cams on the edge of the stacking disc.
  • the cam blocks further collapse of the stacking disks and thus supports the two stacking disks against each other.
  • At least one cam is directed inwards. As a result, the stacking disc following in the stacking direction, which rests against the inside of the raised edge, are blocked by the cam, so that this stacking disc can be supported on the cam.
  • a particularly advantageous variant provides that viewed in the stacking direction, the first cavities each lie above one of the first stacking disks, and that the second cavities each lie above one of the second stacking disks. Thereby, the first cavities and the second cavities can be excellently separated from each other fluidly.
  • viewed in the stacking direction means that one element, viewed in the stacking direction, over another element is stacked in the direction of the other element. Accordingly, an element that is under another element viewed in the stacking direction, offset from the stacking direction is arranged offset to the other element.
  • cams are formed in the edge of the second stacking disks.
  • the cams can prevent slippage of the first stacking discs and thus stabilize the second cavities in the region of the second openings of the stacking discs.
  • Another particularly favorable solution provides that the first fluid and the second fluid are passed in opposite directions of flow through the stacked plate heat exchanger.
  • a heat exchanger is formed in countercurrent principle, which allows a very effective heat exchange between these two media.
  • the invention is based on the general idea of providing a charge air cooler with such a stacked plate heat exchanger as described above, wherein charge air of a charging device is the first Fluid is passed through the first cavities and wherein a cooling medium, such as cooling water, is passed as a second fluid through the second cavities.
  • a cooling medium such as cooling water
  • the invention is based on the general idea of equipping an internal combustion engine with a charging device with a charge air cooler as described above, wherein charge air of the charging device is cooled by the charge air cooler.
  • the illustrated unclaimed first embodiment of a stacked plate heat exchanger 10 is used in a charge air cooler for a supercharged internal combustion engine.
  • the stacked plate heat exchanger 10 has a plurality of stacked disks 14 stacked on one another in a stacking direction 12.
  • the stacked-plate heat exchanger 10 has two types of stacking disks 14, namely first stacking disks 16 and second stacking disks 18.
  • the stacking disks 14 have a peripheral edge 20 set up in the stacking direction 12.
  • Cavities 22 are formed between the stacking disks 14, wherein first cavities 24 and second cavities 26 alternate in the stacking direction 12.
  • the stacking disks 14 have first openings 28 which are arranged in an end region 17 of the stacking disks 14 lying in the longitudinal direction 15 and in second openings 30 which are arranged in the edge regions, for example in a semicircle around the first openings 28.
  • a middle region 13 lies between the two end regions 17.
  • the stacking disks 14 are in addition to the erected edges 20 embossed to form the cavities 22 between the stacking disks 14.
  • the first stacking disk 16 is raised in the stacking direction relative to a base surface 33 in the center region 13 of the first stacking disk 16.
  • the region 19 of the at least one second opening 30 is opposite to the stacking direction 12 lowered.
  • the stacking disks 14 abut one another in the area 19 of the at least one second opening 30 when a second stacking disk 18 lies above a first stacking disk 16.
  • the stack disks 14 form a spacing in the region 19 of the at least one second opening 30 relative to one another when a first stacking disk 16 is arranged above a second stacking disk 18 and thus at least partially form the second cavity 26 there.
  • At the areas 19 of the at least one second opening 30 around the at least one second opening 30 around sealing surfaces 29 are formed, which bear against sealing surfaces 29 of the adjacent stacking disks 14.
  • the second openings 30 are sealed against the first cavities 24.
  • the first openings 28 have a peripheral upstanding edge 31 which is erected from the base surface 33 of the stacking disks 14 in a direction opposite to the direction in which the respective areas 19 of the at least one second opening 30 rise.
  • the edges 31 of the first openings 28 are set up in the opposite direction to the stacking direction 12
  • the edges 31 of the first openings 28 are set up in the stacking direction 12.
  • the height of the edge 31 of the first openings 28 is less than the elevation of the area 19 of the at least one second opening 30.
  • the second extend Cavities 26 from the region of the second openings 30 along the entire length of the stacked plate heat exchanger 10 between the second stacking disks 18 and the overlying first stacking disks 16.
  • edges 31 of the first openings 28 of two adjacent stacking disks 14 abut each other.
  • sealing surfaces 29 are formed on the edges 31. The sealing surfaces 29 seal the first openings 28 against the second cavities 26.
  • the second cavities 26 in the region of the second openings 30 have a greater height and taper towards the central region 13.
  • the first cavities 24 also taper towards the center region 13 of the stacked plate heat exchanger 10. This is because in the end regions 17, the first cavities 24 and the second cavities 26 are arranged laterally separated from one another, and thus the height between the stacking disks 14 need not be shared.
  • the first cavities 24 and the second cavities 26 in the center region 13 of the stacked plate heat exchanger 10 in the stacking direction 12 are separated from each other and extend over the entire surface of the central region 13 of the stacked plate heat exchanger 10. Therefore, the first cavities 24 are tapered and the second cavities 26 respectively from the end portions 17 toward the center hole 13.
  • Two fluidically separated fluid passages are formed in the stacked plate heat exchanger 10.
  • a first fluid passage is formed through the first cavities 24 and a second fluid passage through the second cavities 26. These fluid passages are in thermal contact with each other via the stacking disks 14, so that a heat exchange between the two fluid passages is given.
  • a first fluid for example charge air
  • a second fluid for example a coolant
  • the flow takes place in the opposite direction, so that a counter-current arrangement is given and thereby the heat between the first fluid and the second fluid can be exchanged particularly effectively.
  • the first openings 28 are in fluid communication with the first cavities 24, and the second openings 30 are in fluid communication with the second cavities 26. Via the first openings 28, the first fluid can be passed through the first cavities 24. Via the second openings 30, the second fluid can be passed through the second cavities 26.
  • the stacking disks 14 abut one another in the end regions 17 of the stacking disks 14 in the region 19 of the at least one second opening 30, but only if the second stacking disk 18 is arranged above a first stacking disk 16. If a first stacking disk 16 lies above a second stacking disk 18, only an insufficient support between the stacking disks 14 is provided in the end region 17 of the stacking disks 14. As a result, the stacked-plate heat exchanger 10 can be compressed at the end regions 17 in the stacking direction 12, which makes it difficult to assemble the stacked-plate heat exchanger 10. In addition, this can cause leaks.
  • a support device 32 is provided, which stabilizes the distance between the stacking disks 14, in particular between second stacking disks 18 and first stacking disks 16, which are each arranged above one of these second stacking disks 18.
